Presentation / Conference Contribution
ZHENG, X., Smith, L., Moring, A., & Wood, C. (2019, October). Refined assessment and comparison of airtightness measurement of an indoor chamber using the blower door and Pulse methods. Presented at 40th AIVC - 8th TightVent - 6th venticool Conference, Ghent, Belgium

Previous studies have compared the airtightness measurement of test enclosures utilising both the novel Pulse technique and the conventional blower door method. Discrepancies between results of the two test methods were observed and it was concluded...

An extended pressure range comparison of the blower door and novel pulse method for measuring the airtightness of two outdoor chambers with different levels of airtightness (2018)
Presentation / Conference Contribution
Wood, C., Zheng, X., Vega Pasos, A., Hsu, Y.-S., & Smith, L. (2018, September). An extended pressure range comparison of the blower door and novel pulse method for measuring the airtightness of two outdoor chambers with different levels of airtightness. Presented at 39th AIVC - 7th TightVent & 5th venticool Conference

The steady pressurisation method measures the building leakage in a range of high pressures, typically 10-60 Pa. It is implemented by creating a steady pressure difference across the building envelope and measuring the corresponding airflow exchange...

Experimental study on the measurement of building infiltration and air leakage rate (at 4 and 50 Pa) by means of tracer gas methods, blower door and the novel pulse technique in a detached UK home (2018)
Presentation / Conference Contribution
Vega Pasos, A., Zheng, X., Sougkakis, V., Gillott, M., Meulemans, J., Samin, O., Alzetto, F., Smith, L., Jackson, S., & Wood, C. J. (2018, September). Experimental study on the measurement of building infiltration and air leakage rate (at 4 and 50 Pa) by means of tracer gas methods, blower door and the novel pulse technique in a detached UK home. Presented at 39th AIVC - 7th TightVent & 5th venticool Conference, Antibes Juan-Les-Pins, France

Air infiltration contributes to a heat loss typically representing up to one third of the heating demand of a building. The building airtightness, also quantified as air leakage, is the fundamental building property that impacts infiltration. The ste...

Experimental studies of a pulse pressurisation technique for measuring building airtightness (2018)
Presentation / Conference Contribution
Zheng, X., Cooper, E., Zu, Y., Gillott, M., Tetlow, D., Riffat, S., & Wood, C. (2018, August). Experimental studies of a pulse pressurisation technique for measuring building airtightness. Presented at 17th International Conference on Sustainable Energy Technology (SET 2018), Wuhan, China

A pulse pressurisation technique is developed and utilised for determining building leakage at low pressure, based on a 'quasi-steady pulse' concept. The underlying principle of the technique is to subject the building envelope to a known volume chan...

QUB/e: Validation of a transient method for determining whole building thermal performance and building element U-values in situ under actual operating conditions (2018)
Presentation / Conference Contribution
Sougkakis, V., Wood, C., Meulemans, J., Gillot, M., & Cox, T. (2018, August). QUB/e: Validation of a transient method for determining whole building thermal performance and building element U-values in situ under actual operating conditions. Presented at 17th International Conference on Sustainable Energy Technologies – SET 2018, Wuhan, China

Growing evidence in recent years has suggested that a difference exists between the design and the as-built thermal performance of UK dwellings. This difference commonly known as the ‘performance gap’ may have serious implications on the UK governmen...

Presented at 39th AIVC - 7th TightVent & 5th venticool Conference, Juan-Les-Pins, France

The air infiltration of a building, which fundamentally depends on its airtightness, can be a significant contributor to its heat loss. It can also be affected by other factors such as external terrain, leakage distribution, sheltering factor and env...
